I ordered this to put behind my router box nb4 SRF because the wifi is g and wanted to have n. I hesitated, thinking to buy another site a box NB6 opportunity and then I embarked on this router. Note that I am not any specialist in the field of networks .I had taken information on the web to configure the same router that promised delicate: The paper is in English, only the installation CD is in French. How to configure the router and the box, only questions I ask myself! I connected the router to the box as it is clearly stated on the CD, I followed step by step instructions that are simple, and I just turned off the wifi on the final box SFR. so the router manages the wifi, and manages the tv box works normally, telephony too. The wifi signal is excellent throughout the apartment, I added a USB key of the same mark on my old laptop to 4 or 5 euros and I'm 300 Mbps. Last thing, the router is very discreet, pretty .For the moment as well, especially regarding SFR nb4 have a box and want to benefit from the free wifi No bother.
